Context
A 10b5‑1 plan lets insiders pre‑arrange trades and is commonly used for tax or estate planning; trades under such plans are generally considered pre‑scheduled rather than discretionary. Sales do not inherently signal a negative view of the company—purchases are typically considered more informative about insider sentiment.
